. In Switzerland November 30, 1948 '1' Claim. (arm-2) vThe object of thepresent invention is a fuelissuing slot or prepayment machine which maybe used, for instance, for filling cigarette, cigar or pipe-lighterswith fuel. d

The coil-operated fuel-issuing machine in accordance with the inventionis designed on the principle whereby a fuel reservoir communicates witha cylinder and the latter communicates via a pipeline, with a deliverynozzle, a piston controlled by a coin-operated mechanism being movablyarranged in said cylinder and impellin an accurately metered quantity offuel to the delivery nozzle. I

The enclosed drawing illustrates a typical embodiment of the invention,in which drawing;

Fig. 1 is a vertical section, whilst Figs. 2 to 4 are details of thecoin-operated mechanism. 7 I

The coin-operated fuel-issuing machine shown comprises a cabinet Iclosed at the top by a lid 2. In the cabinet I is accommodated a fueltank or reservoir 3 which is in turn closed at, thetop by a lid 4. Acylinder 5 is mounted in thebottom of the tank 3, a pipe-line 6 beingconnected to said cylinder 5 and leading via a valve unit 1 andaball-retaining valve 8to thedeliverynozzle 9. This nozzle is of suchdesign (not shown in the drawing) that its outlet aperture opensautomatically when a container to be filled is pressed up against saidnozzle, whilst it also closes automatically when said container to befilled is removed from said nozzle. A pump-piston l mounted in thepiston guide II and arranged on a piston-rod l2 co-operates with saidcylinder 5. Said piston-rod passes through the lid 4 and is subject tothe action of a spring l3 which bears at one end against a washer I4which in turn bears on the lid 4-, and at its other, lower end against atransverse cotter l5 in the pistonrod l2. The spring [3 tends to forcethe pistonrod l2 downwards, and thus to force the piston I0 into thecylinder 5. At its upper extremity the piston-rod 12 carries by means ofa screwthread I6 a forked element H the top of which is pierced by aspindle [8 on which a roller I9 is sov mounted as to be looselyrotatable. One arm 20 of a bell crank 2| projects into said forkedelement H, the other arm 22 of said bell crank bearing on a roller 36 ofthe coin-operated mechanism.

Said coin-operated mechanism is shown in detail, in various positions,in Figs. 2 to 4. As can be seen from Fig. 1, the coin-operated machineis provided with a chute 24 which leads downwards and to the rear thecoin inserted through the slot in the front wall of the machine. Be-

' slot 26.

low the aperture of the chute 24 a slot 26 is provided in a slide 25, sothat any coin inserted into the slot of the machine and droppingrearwards down to the chute 24 is able to enter said It is preventedfrom falling through said slot 26 by a pin 21 mounted in a positiontransversal to the longitudinal axis of said slide and slidable in thelatter. A leaf spring 28 which embraces the head of said pin 21 tends tomaintain said pin in the position shown in Fig. 3. As this figure shows,said pin 21 is provided with a recess of slot 29 the breadth of whichcorresponds to the breadth of the slot 26. A spring 3| is secured to apin 30 in the slide 25, the other end of said spring being fastened to apin 32. Said spring 3| tendsto draw the slide 25 in an outwarddirection, i..e., to the left in Figs. 2-4. At its extreme end the slide25 carries a screw pin-33 on which the pressure or ripping unit 34 isfitted. By means of the latter the slide 25 can be moved against theresistance of the spring 3|. In the slide 25 a roller 36 is mounted on aspindle 35. Said roller 36 is so mounted on-the spindle as to beslidable in an axial directiQn, anda spring 3! tendsto presssaidrolleragainst a wall 38. In this wall is provided a slot 39 theshape of which is illustrated in particular by Figs. 1 and 2. This slothas a circular extension 40 through which the annular flange 4| of theroller 36 can pass. A second, corresponding extension 42 (Fig. 1) islocated in the slot 39. Behind the wall 38 a leaf-spring 54 is securedby means of a rivet 43, the shape of which is seen in Figs. 3 and 4.

The coin-operated machine functions in the manner described hereunder:

Assuming that the fuel tank 3 is completely or at least partly filledwith fuel; if a coin is inserted into the chute 24, it falls on to theslot 26. If the coin inserted is too small, it automatically falls rightthrough. If however, the coin is of the correct size required, it comesto rest on the pin 21. If the stud or button 34 is now pressed, thussliding the slide 25, the head 44 is forced up against the guide surface45 of the coin-insertion device. As is shown in Figs. 3 and 4, saidguide surface 45 is so designed that it displaces the head 44, and withit the pin 21, in a transverse direction to the direction of movement ofthe slide 25, said displacement being all the greater the further saidslide is moved to the right. At a given moment, the slot or recess 28will coincide with the slot 26, the coin then dropping into a, cashboxnot shown in the drawing. Whilst the coin, designated by the numeral 46in Fig. 2, was bearing on the pin 21, it was brought, by the rearwardmotion of the slide 25, up against the retaining hook 41. The fore end48, of hooked shape, of said retaining hook rests, when the mechanism isat rest, in a recess 49 in the slide 25. The rear end of the retaininghook 4'! is subject tothe, action of a, spring 50 the upper endof wmugbegrs a 'infstjthe hjolthad 5!. When the slide 25 containing the coin'46 is pushed back, said coin pivots the fore end 48 or the hook 4! in aclockwise result that said fore end 481's witli'dfaZwhTf-i'bhi the slide25, i. e., from the recess 49, when tinuance of the inwardmovementoftthejsliueifipossible.
